Sometimes you create something that has more than paper and for that you need a really good adhesive. For this frame I used ScraPerfect amazing glue: The Best Glue Ever. I didn't need any other glue. It works with everything!
First I painted the frame with white acrylic color. Then I adhered the papers on it. I created the rainbow by threading the buttons into a metal wire. I attached the wire to the frame with the Beat Glue Ever and it holds perfectly. I've also adhered the other buttons with this great glue.
